Friedrich Wilhelm Kämper, the only son of Walter Kämper, born on 1 February 1925, like many of his generation, did not return home after the Second World War.
After Walter Kämper's death, his wife Elly Kämper, born Dresel, continued to run the business. It was not until April 1977 that a cross-generational transition took place, when niece Hannelore Müchler and nephew Wilhelm Richard Kämper joined the company in equal shares.
Wilhelm Richard Kämper took over the management of the local business. Hannelore Müchler, based in Mülheim an der Ruhr, acted in the role of wife and mother, maintaining contact with the company. Through her responsibility for payroll accounting, she maintained regular contact with the employees.
